Vintage 1970's Amber Handblown Glass Pitcher & Tumbler Set, Collectible Colored

Gorgeous vintage 1970's amber Handblown glass pitcher & tumblers (5) set. The pitcher is tall and heavy. The color is very rich with good clarity. Put her has a twisted clear glass applied handle and a clear round footed base. The spout is rolled with the 'wings' to keep ice cubes inside pitcher when pouring. The tumblers are smooth and an upside-down pear shape. They also have clear round footed bases. The set is unmarked and I could not find an exact copy online at time of this posting. Some of the elements of design / color did match glass produced in Italy or Poland. Found disjointed elements that look like pieces from Empoli, Stevens & Williams and Amberina Glass- but the similarities may be a product of its production eras' style aesthetics. Very high quality set, the pitcher is sturdy and heavy / cool with a generous glass pouring. The handle is well-applied and secure and large enough to handle the weight of this larger sized pitcher. The glasses fit well in the hand and the glass thickness goes from thick in the base to quite thin at the lip. Would make a nice housewarming gift, glass anniversary gift (3 year anniversary).  Size: Pitcher- 10.5 tall x 8.5 spout tip to handle edge. Tumbler- 5 tall x 2.75 diameter at rim.  Condition: Overall very good vintage condition. Light signs of use here and there. One tumbler has a tiny hairline fissure extending 0.5 down from rim- It isnt always visible in every light- you'd have to look for it and the rim is not chipped.
